To change the language version on the Desktop Version: On the version you have installed, open a wallet (Sample Wallet password is 123), and in the Find box at the top, please type in "::language" (without the quotes) and it will pop up a menu for you to choose the language you want. Select the preferred language, Exit CodeWallet, launch CodeWallet and you will see your preferred language. On the Mobile Versions simply reinstall the mobile version and select the desired translation.
